Application filed January 15, 1919. Serial l lo. titted.

To all whom it may concern:

Be it known that I, Gnonen HARDY, a subject of the King of Great Britain, residing at Portneuf Station, Province of Quebec, Canada, have invented certain new and useful Improvements in Regulators for Paper- Making Machines; and l do hereby declare that the following is a fulhclear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

The present invention relates to paper making machines, and more particularly to a device for regulating the flow of paste from the paste reservoir to the machine for forming the paste into paper. An object of the present invention is to provide a regu' 'lator which will automatically control the flow of paste from the paste container.

With the above and other objects 1n view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which re course may be had that come Within the scope of the'claims Without departing from the spirit of the invention or sacrificing the efliciency of the same.

lln the accompanying drawings Figure 1 is a vertical section through the paste reservoir showing the invention applied thereto. s

Fig. 2 is a detailed plan view of the valve operating, mechanism; and,

Fig. 3 is an enlarged detail section showing the flow controlling valve when in opened or closed position.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by," similar reference characters throughout the several views. I

The numeral 1 indicates a tank or a suit" able reservoir in which the paste is stored or mixed, and which paste is to be formed into paper. Leading from the tank 1 is an elbow is a pipe 23.

charged through the opening i. From thisit can be seen that the paste may flow from the tank 1 through the pipe 3 into the basin 5 and be delivered to the paper making machine in the manner as shown in Fig. i.

As stated in the outset of the specification. it is the purpose of the invention to regu late the flow of this paste from the tank 1 to the reservoir 5 and to accomplish this object I provide a valve 8. This: valve s comprises two panels 9, and when these panels are in alinemont as better shown in dotted lines in the Fig. 3 of the drawing. The outlet opening is closed stopping; the fiow of paste from the reservoir, and when they are in a full line position, this outlet is opened and these two panels 9 are each pivotally mounted upon a shaft 10, the upper end of which extends through the elbow 5?; and terminated by an arntll. The valve 8 is automatically operated by a float 12 sus pended within the basin 5 so as to move in a vertical direction according to the specific gravity and height of the paste traveling through the basin 5. This float is couuectml to the said panels 9 through a mechanism as follows:-

In the upper end of the float is extending a rod 13, which pivot/ally coiu'iccted to one end of a link it, and the other end of said link is pivotally supported by a brachct 15 rigidly connected to the elbow 2. also rip;- idly connected to the bracket 14.- is an shaped rod 16, the opposite end of which is provided with a guide ll" for the rod Rigidly adapted to the link let is a vertical rod 18, pivotally connected to an end oi a rod 19 having a turn buckle 20 arranged therein and the opposite end is connected by a toggle-joint ill. to the two .llillis each pivot-ally CORIlGCtQtl to the arms 11.

l roin this constructicui, it is oln'ious that as the float 12 descends the valve ti will he opened but as the float rise the valve Fl will be closed.

-Th1:'ough this valve (hfIl'l'l-t0llll1; means, it is obvious that when a lilate mixture of paste is flowing, from the reservoir l, into the till El ll l lltl lltl paste to basin '5, the float 12 will descend thereby opening the valve 8' permitting thisslight flow freely from the tank 1, but if the tank 1 is provided with a heavy paste, the Weight will cause the float 16 to rise, thereby moving the panels 9 so as to limit the flow of paste from the tank 1 to the paper making machine, sheets of paper of the same thickness will be made through the manufacture.

Having thus fully described my invention, what I claim as new and desire. to secure by Letters Patent is i g 1. The combination with a tank'having an outlet therein, of an elbow connected to said outlet, a pipe leading from said elbow, a

' vertically extending basin connected to the lower end of said pipe, a float mounted within said basin, a valve pivotally mounted within said elbow, a crank arm connected to said valve, and links connecting said crank arm with said float, whereby when the float is raised or lowered, said valve will be opened and closed substantially as and for the purpose specified.

2. The combination with a tank having an outlet pipe leading therefrom, a valve arranged within said outlet pipe, a basin secured to the outer end of said outlet pipe, a trough encircling the upper end of said basin, said trough having an outlet opening, a vertically movable float arranged within said basin, and means for connecting said float with said valve whereby when the float is raised and lowered said valve will be opened or closed.

3. The combination with a tank having an outlet pipe leading therefrom, a valve pivotally mounted within said outlet pipe, a vertically extending basin connected to said outlet pipe, the upper end of said basin be- GEORGE HARDY.
